Our invention relates to cloth doubling ma chinesof thekindin which the travel of the edges of the web is automatically regulated and guide bars serving to foldthe web are provided stationarily while pairs of guide rollers, for each edge of the web'are disposed above these bars which rollers are controlled electro-magnetically, a feeling mechanism being provided thefeelers of which are acted upon by, the web and regulate thetravel of the V followingmanner:

web. Our invention has; for its object to improve this feeler mechanism which is of the design forming the subj cot-matter or ourocopending patent application Serial Number and more reliable in operation.

In order that our invention may be clearly understood and readily carried into effect, an embodiment of the same is illustrated by wayof example in the accompanying drawings in whichchine fitted with the above-mentioned edge regulating mechanism,

Figure 2 is a fragmentarytop view thereof,

Figure 3 is an elevation of a pair of edge guide rollers used, on an enlarged scale,

Figure 4 is an elevation showing the feeling mechanism designed in accordance with the invention, likewise 0n enlarged scale, Figure 5 is atopview thereof,

Figure 6 is'a detail showing the feeling parts of the mechanism,

Figure 7 is a side elevation thereof, and Figure 8 shows'the wiring diagram of the whole arrangement- 8 Referring to these drawings, 9 denotes the usual doubling table below which are arranged the two stationary folding bars 10. On these bars or on any other suitable carrier is mounted a fixed member 11 which has freeend forked, asto be seen best'Figuiies A and1 5'.

The bars 24a and 16 are adjusted first in the head 23 of the support 11 in such a manner tically when the folded web travels in its normal position. fvVhen the two edges of the web, marked by w and 3 in Figure 6, exactly reg-' ister with one another during their downward travel,'-thenthey uniformlytouch the rocker 17 7 so thatb'othcontacts 19 21; andQO, 22 remain open. When however for instance the edge a: deviates from its normalposition .1 relatively to edge y, as indicated bythe arf row in Figure 6, the rocker 17 swings horizon tally about the bar 16 so that the contact j ;19,21is closed, whilst contact 20, 22 is opened 7 still farther.
